Document Type and Number:
Japanese Patent JP6872103
Kind Code:
B2
Abstract:
A change degree deriving apparatus includes a receiving unit and a change acquiring unit. The receiving unit receives image data and new product image data. The image data is obtained by capturing an object, through/from which a light source having a known spectral characteristic is transmitted/reflected, under a condition with no influence of sunlight. The new product image data is obtained by capturing the object in a new product state under an identical condition. The change acquiring unit acquires a change degree of the object by comparing a ratio of first data on a first specific color to second data on a second specific color that is different from the first specific color in relation to the received image data, with a ratio of third data on the first specific color to fourth data on the second specific color in relation to the received new product image data.
